Grading Rubric:
A successful short-answer response accomplishes all three tasks set forth by the prompt. Each part of the prompt is worth 1 point, for a total of 3 possible points.
(a) To earn the point, the response must describe a significant historical similarity between the impact of trade exchanges in the Atlantic economy on Africans and American Indians. The response should provide a specific example of how trade exchanges affected both groups in a similar way, such as the forced migration and displacement of populations, the disruption of traditional societies, or the exposure to new diseases.
(b) To earn the point, the response must describe a significant historical difference between the impact of trade exchanges in the Atlantic economy on Africans and American Indians. The response should provide a specific example of how trade exchanges affected the two groups differently, such as the enslavement of Africans for labor in the New World, versus the often violent displacement of American Indians from their ancestral lands.
(c) To earn the point, the response must explain a specific historical effect of the Atlantic economy on the British colonies in North America. The response should provide a specific example of how the Atlantic economy influenced the development of the British colonies, such as the growth of cash crop economies, the increase in trans-Atlantic trade, or the development of a class system based on wealth and race.
